Rpl emulator new update

[mfleming]

I take it for granted from your various posts that you rely on the underlying Prime functions rather than writing your own routines to match those in the HP48. I thought going through the Owners Manual would be a more disciplined approach to just banging on the keys to see what happens At any rate, it would result in me trying all of the HP48 functions, skipping the unimplemented graphics commands.

Your post does raise a question though: Do you expect the Prime to be in CAS or Home mode when starting the simulator, or does it matter? At any rate, here's some feedback using the 22May2017 version of the software on the physical Prime using the Owners Manual, Chapter 1 for guidance.

*Functions UPPER and LOWER work correctly
*The ON key doesn't cancel a command line
*Shift-Clear clears the stack
* SHIFT-Sto with value and variable name on stack works. An alpha string entered without quotes is assumed to be a variable name if it doesn't match a command name (The HP48 wants single-quotes around a name; not necessary here, I think)
*Can press SHIFT-singlequotes key then a variable softkey to put the variable name in quotes for the purge command
*The various RPN examples and quoted arithmetic expression examples on pages 1-18 to 1-20 work
*Algebraic expressions are in exact format on the stack. The approx function (from D-key menu) or the a b/c key will convert to the decimal result
*In algebraic mode, the X-squared key returns what looks like 2-space-caret rather than caret-2. The key works fine in immediate mode
*The Define function (SHIFT-D) doesn't map to the HP48 DEF command

I've yet to go through all the function keys on the keypad, but I had no problems running through the introductory examples (other than HP48 functions with no Prime equivalent). I've worked a little bit with variables and directories, and will probably focus more on that next.

The code is still a bit fragile. I've seen mistakes do everything from bounce me into the debugger to resetting the Prime (fun!) More later...
